Application filed April 26, 1926. Serial Ne. 104329.

My invention relates to a window ventilator and pertains ;more specifically to ja combined window-sill and ventilator structure that is made so that a window mav be raised'slightly from the sill and the sill plate n'oved on hinge in an. upward direction so ,that a direct or straight draft through the open portion ot the window is thereby prevented. The structure I have designed afiords a dependable ventilator and when the same is ,closed down flat will provide the usual sill for the window so that it avoids the use of an additional frame such as is usually employed for window ventilaters which have to be removed and stored away when not in use. Among the objects which I have in mind in designing my improved -window-sill and ventilator are dependability in operation, compacjtness in arrangement and disposition of parts, novelty in Construction and econony in manufacture.

I prefer to Carry out my invention in substantially the manner hereinatter fully described and as more particularly pointed out in the claims, reference being made to the accompanyn; drawings that form a portion of this specification.

In the drawings:- a Figure 1 is a perspective of a window frame and sash showing my improved sill and ventilator in use, thesill being shown in a raised position for the purpose of ventilation.

Figure 2 is a top plan of one end of the sill. showing the ven'tilator closed to provide a fiat sill, the window being shown in horizontal section.

F igure 3 is a transverse Vertical section on the line 3, 3 of Figure 2 looking`in the direction of the arrows and showing the sill partially raised for the purpose of ventilation.

In the drawings, which are in a sense schematie :for the purpose of illustrating a preferred or typical embodiment of my invention, I have employed similar reference characters to designate like parts wherever they appear throughout the several views. Referrng to Figur-e 1, it will be seen I have adapted my device to window frame and sash of the ordinary Construction, with the excepton that the standard sill is modied to the extent of providing the same with a tiltable plate 1 that is hinged along .its edge neares't the window sash by means of butt hinges 2 so that the inner edge of the plate 1 which is inside or farthest from ,the window, may be raised or lowered as desired. About mdway of each end'edge of the plate it is provided with a small bolt 4 that p'o jects outwardly from said edges and is pro-- Vided upon `its outer threaded end with a thumb-nut 8. A slotted or strut brace 5 co operates with the shank of the bolt 4: and at one of its ends is pivotally mounted upon a lateral stud 7 projecting from ,the bracket or mounting plate 6 that is Secured to the adjacent portion of the window-sill base.

.As seen in Figure 1, there are two of these brace structures, one at each end of the plate 1. The window-sill 8 has a cutout recess or depression 9 of substantally a depth corresponding with the thickness of the sill plate l and of substantially the same shape and dimensions as the plate so that When the latter is lowered and out of use it will seat in the depression and lie flush with the upper surface of the sill so that a neat appearance is presented. The brackets 6 are Secured 'to the transverse end edges ot' the recess and there ,are provided small notches or ofi'sets 10 adjaccnt thereto for the purpose of receiving the thumb-nut 3 and any projecting portion of the shank of When it is desired to ventila te with fresh outside air, the window may be raised a few inches above the sill and the plate 1 is then raised upon its hinges 2 into any desire d inclined position as suggested in Figures 1 and 3 Where it is maintained by tightening the thumb-nuts 3 against the outer surface of the brace or strut 5. The slot in the brace or strut 5 extends to adjacent the end thereof, thereby permitting of a wide range of adjustability and it also thereby prevents the vent-ilator plate being raised to such an extent that it might fall outwardly into engagement with the glass or window pane and damage the same. When it is not desired to use'the plate 1 as a ventilator, the thumbnuts 3 are loosened and the plate is lowered flat in the recess of the sill, where said plate and all of its parte will then be flush below the plane of the top of the sill, so as to not interfere with the functioning of the struoture as a window-sill. If desired, where the window-sill is comparatively narrow, the plate 1 may be divided l'ongitudinally in two parts and hinged together so as to be collapsed when the same is lowered to form a window-sill, and it Will be understood that the surfaces of the recess or depression and the faces of the plate are painted or finished in the same manner as the other portions of the window frame and sash in order to harmonize With or maintain the decorative scheme of the room in which the Ventilator is installed. It will be obvious that other modifications may be made without departing from the principles herein disclosed and I desire it understood that all of such changes are tully contemplated as coming within the scope of my appended claims.

lVhat I claim is 1- 1. A combined window-sill and window entilator comprising a sill having a depression therein, a plate normally disposed in said depression and hinged along its edge nearest the window, said plate adapted in its normal position to provide the upper surface of the window-sill, and means for maintaining said plate in divers positions when moved upon its hinges.

2. A conbined window-sill and Window ventilator comprising a sill having a longitudinally elongated depression therein, a movable plate normally seated in said depression and in said position providing the upper surface of the sill, braces for maintaining said plate in divers angular posi to-ns with respect to said sill and pivotally connected to one of said elements, and pin and slot adjustable connections between said braces and the other of said elements.

3. A combined window-sill and window ventilator comprising a sill, an elongated plate hinged to said sill along its longitudinal edge nearest the window, and a brace pivotally mounted at one end 'on the sill and having its intermediate portion coacting with the plate to assist in supporting the latter when it is moved upon its hinge, the arrangement of the brace and plate being such that the latter may be disposed fiat upon the sill whe-reby the brace will be fitted snugly at the end of the plate flush with the top thereof.

4. A combined window-sill and window Ventilator comprising a sill, an elongated plate hinged to said sill along its longitudinal edge nearest the window, a projection upon an end edge of said plate, a brace pivotally connected at one end to said sill and having a slot thei-ein that coacts with said projection, and means for clamping' said projeotion and brace together to maintain said plate at divers angles to said sill, the arrangement of the brace and plate being such that the latter may be disposed flat upon the sill whereby the brace will be litted snugly at the end of the plate flush with the top thereof.

5. A combined window-sill and window ventilator comprising a sill having an elongated depression in its upper surface, an elongated plate hingedly connected to the edge of the recess nearest the window, bolts projecting 'rom the end edges of said plate, b 'aces pivotally connected at one end to the end edges of said depression and having slots that co-operate with the shanks oli said bolts, wherebv to pcrmit said plate to bc moved upon its hinged edge to divers an gles to the plane of the silL and thumb-nuts screwed upon the bolts and adapted to clamp against said braces and maintain said plate in its divers adjusted positions.
